Semi

I do not see the point of duplexing... especially while hunting and if your are going to use real BP - even a smal duplexload - you going to have to clean the gun right away any way.

I my limited shooting with BH - it is no more accurate than T7 and only creates a bit more velocity... in fact the POI really does not change significantly...

Then again I read somewhere of a person doing just as you have suggested and it works very well.
